Merge branch 'master' into pr263/PierreBdR/ts-domain-error-in-stage/master

Introduce MPIU_Allreduce() to detect cases where all processes that share an MPI comm do not call the same sequence of MPI_Allreduce()
This is a bug that can be difficult to track down.

Get 3.6.2 patches

* master: (1360 commits)
remove nasty memory leak with CUDA code when using block Jacobi with multiple blocks per process
print abs in Fortran test example in order to have same result with real and complex builds
changed outdate mpirun and -np to mpiexec and -n
force sqrt to be taken in the precision of PetscReal in fortran examples
continuation line too soon for some compilers
stop configure if user selected C++ clanguage, single precision, complex combination since we do not support it
fixes for Fortran examples to compile cleanly in single precision that do not involve complex numbers
fixes to Fortran examples to compile cleanly in single precision complex
fix previous mistake
must cast 1. to PetscScalar before dividing by a PetscScalar (C++ complex class is terrible)
must cast 0.0 to PetscScalar before comparison with a PetscScalar
changed order of suggested locations of downloadable PETSc to Barry's preference
Increase patchlevel to 3.6.2
remove debug print statement from two commits before
remove debug print statements I accidently left in the last commit
PetscDraw: Fix dummy definition of PetscDrawCollective{Begin|End}()
remove cleanupMumps flag from MatDestroy_Mumps() it should always free the memory it allocated Bug detected while adding features to libMesh
improved viewing of fractional counts in xml nested log viewing fixed bug in output of doubles to xml nested log files
chombo: build only libs - not examples
fix typo. 'gcc-4.8 --with-cxx-dialect=C++11' gives a warning with this line - even though its in a #ifdef thats never enabled.

* master: (151 commits)
moved PCTELESCOPE comment into users manual since no one will see the comment
message in makefile about hypre bugs causing test crashes
remove use of some unitialized variables, remove use of "dummy" entries in Vec and IS since Dave May thought they could not be of size zero. Now three telescope tests give no valgrind errors
code sent unitialized data via MPI and allocated too large space for creating indices
Force generateetags.py to use /usr/local/bin/ctags before using ctags because the ctags provided with Apple XCode gets confused by function usage in .tex files and does not make proper tags for TSSolve() and many many others
Optimized version of snes/examples/tutorials/ex1f.F produced incorrect results when lx_v() and lf_v() were declared as of dimension 1 with optimzed builds only. Cannot explain exactly why this happens but since we are using VecGetArray() from Fortran we are gambling with the compiler regardless
make the PetscRandom object used in GAMG to be a public object that can be controlled via the options database. This allows the same example to produce the same results with real and complex numbers by using the option -pc_gamg_random_no_imaginary_part
added parallel tester for examples. Crude but it reduces a basic alltests on my laptop from 25 minutes to 7 1/2 minutes.
remove unneccessary if
fix the problem for ex9 which involves multiple TSSolve calls
shortened the time of several test examples
decrease dramatically the time used by several test examples that take more than a minute on may machine with debug mode
Some of the vectors created in MatNullSpaceCreateRigidBody() were not normalized to 1
fix strange PCTelescope struct name of P which caused duplicate symbol error on some systems cleanup use of PetscMalloc and PetscFree for telescope for modern PETSc standards replace semiredundat to telescope in makefile that runs test examples
SNESUpdateCheckJacobian: make relative norm output syntactically correct
DMCompositeGetGlobalISs: document Fortran interface
fix warnings on bsd. Also fix usage of PetscFunctionBegin/Return
Making an even bigger mess, I cannot explain why this is not in the branch
hypre: update with "Bug fix for Parasails; src/ksp/ksp/examples/tutorials/ex10.c runex10_16"

Merge branch 'master' into knepley/fix-plex-examples

* master: (75 commits)
increase the size of the ex25.c multigrid example so that the eigenestimator does not produce numbers that depend on machine roundoff and thus are different on different OS/hardware and produce different test restults. Previously the GMRES converged to 16 digits in 4 iterations and spent the next 6 churning but that churning produced different eigenvalues which produced different convergence for the multigrid method

Merge branch 'barry/fix-nonew-notcollective/maint' into jed/mat-assembly-perf

Jed this fucking 6+ month running thing in next that is not in master is a royal fucking pain in the ass and
an abuse of git. I think it is not justified to ever have anything in next for more than a few weeks at most.
Either take it out of next if it is broken or put it in master if it is not broken. Hanging around in next but
not master for ever is not a good policy.
